Visual Studio 2017
------------------

To build the Zint library DLL and the command line tool "zint.exe" with PNG
support for x86/Win32:

Install git (https://git-scm.com/downloads)
Install cmake (https://cmake.org/download/)

Open a "Developer Command Prompt for VS 2017" (should be available under the
"Visual Studio 2017" tab in the Start menu).

Make sure git and cmake are in your PATH, e.g. (your paths may differ)

  set "PATH=C:\Program Files\Git\cmd;%PATH%"
  set "PATH=C:\Program Files\CMake\bin;%PATH%"

Download zint, zlib and libpng by going to the directory you want to clone them
into:

  cd <project-directory>

and cloning each:

  git clone https://git.code.sf.net/p/zint/code zint
  git clone https://git.code.sf.net/p/libpng/code lpng
  git clone https://github.com/madler/zlib.git zlib

First build zlib:

  cd zlib

  nmake -f win32\Makefile.msc clean
  nmake -f win32\Makefile.msc LOC="-DASMV -DASMINF=" OBJA="inffas32.obj match686.obj"

  cd ..

and then lpng:

  cd lpng

  cmake -G "Visual Studio 15 2017" -DCMAKE_BUILD_TYPE=Release^
        -DPNG_BUILD_ZLIB=ON -DZLIB_INCLUDE_DIRS=..\zlib^
        -DPNG_STATIC=ON -DPNG_SHARED=OFF -B build

  cmake --build build --config Release

  cd ..

If you now open "%cd%\zint\win32\zint.sln" with Visual Studio 2017, you
should be able to build the Release configuration for Win32.

"zint.dll" and "zint.exe" will be in "zint\win32\Release".

To build Zint Studio ("qtZint.exe"), you need to have Qt installed, which
involves signing up for a Qt account and installing the Qt Maintenance Tool.
(https://www.qt.io/download-qt-installer)
Using this tool you can install various versions of Qt and various optional
components.

The following requires the "MSVC 2017 32-bit" component to be installed.

As of writing Qt 5.14.2 is the latest release that includes this component and
is used here. Add the location of this component to your PATH, e.g. (your path
may differ):

  set "PATH=C:\Qt\5.14.2\msvc2017\bin;%PATH%"

Next build the Zint backend Qt library "QtZintDLL.lib":

  cd zint\backend_qt

  qmake backend_qt_zintdll.pro
  nmake clean
  nmake release

  cd ..\..

Then Zint Studio "qtZint.exe":

  cd zint\frontend_qt

  qmake frontend_qt_zintdll.pro
  nmake clean
  nmake release

  cd ..\..

This creates "zint\frontend_qt\release\qtZint.exe". It requires the Zint DLL to
run, so add its location to your PATH:

  set "PATH=%cd%\zint\win32\Release;%PATH%"

You should now be able to run Zint Studio:

  zint\frontend_qt\release\qtZint


Visual Studio 2019
------------------

A solution for Visual Studio 2019 is in sub-directory vs2019. The steps are the
same as for Visual Studio 2017. To build lpng use

  cmake -G "Visual Studio 16 2019" -A Win32 -DCMAKE_BUILD_TYPE=Release^
        -DPNG_BUILD_ZLIB=ON -DZLIB_INCLUDE_DIRS=..\zlib^
        -DPNG_STATIC=ON -DPNG_SHARED=OFF -B build

(note the extra argument "-A Win32"). For Qt, the latest Qt5 version as of
writing to support Visual Studio 2019 is 15.5.2. Install this and the
"MSVC 2019 32-bit" component. Zint Studio can also be built using Qt6.


Visual Studio 2015
------------------

The solution and project files for Visual Studio 2015 have been moved to the
sub-directory vs2015. The steps are almost the same as for Visual Studio 2017,
except that "rc.exe" may not be available. If so, you need to install a Windows
Kit and then update your PATH, e.g. (adjust for version):

  set "PATH=C:\Program Files (x86)\Windows Kits\10\bin\10.0.19041.0\x86;%PATH%"

To build lpng use

  cmake -G "Visual Studio 14 2015" -DCMAKE_BUILD_TYPE=Release^
        -DPNG_BUILD_ZLIB=ON -DZLIB_INCLUDE_DIRS=..\zlib^
        -DPNG_STATIC=ON -DPNG_SHARED=OFF -B build

Recent versions of Qt no longer supply a specific component for Visual Studio
2015 32-bit, but you can use "MSVC 2017 32-bit" or "MSVC 2019 32-bit" instead as
they're compatible.

For information on building a standalone version of Zint Studio using Visual
Studio 2015, see "frontend_qt\howto_build_qzint_using_msvs2015.txt"


CMake and Visual Studio
-----------------------

Zint can also be built using CMake with Visual Studio 2019, 2017 or 2015. The
following example uses Visual Studio 2019 to build for x86/Win32:

As above, cd <project-directory> and clone lpng, zlib and zint into it. Then

  cd zlib
  ml /safeseh /coff /c contrib/masmx86/match686.asm
  ml /safeseh /coff /c contrib/masmx86/inffas32.asm
  nmake -f win32\Makefile.msc LOC="-DASMV -DASMINF=" OBJA="inffas32.obj match686.obj"
  cd ..

(compiling the zlib assembler with "SAFESEH" seems to be required when building
zint using CMake)

  cd lpng
  cmake -G "Visual Studio 16 2019" -A Win32 -DCMAKE_BUILD_TYPE=Release^
        -DPNG_BUILD_ZLIB=ON -DZLIB_INCLUDE_DIRS=..\zlib^
        -DPNG_STATIC=ON -DPNG_SHARED=OFF -B build
  cmake --build build --config Release
  cd ..

CMake needs to be able to find zlib and lpng. One way to do this (requires
Administrator privileges) is to create two sub-directories in
"C:\Program Files (x86)" called "include" and "lib", and then copy

  "zlib\zlib.h", "zlib\zconf.h", "lpng\png.h", "lpng\pngconf.h" and
  "lpng\pnglibconf.h" into "include", and

  "zlib\zlib.lib" and "lpng\build\Release\libpng16_static.lib" into "lib".

You may need to rename "libpng16_static.lib" to "libpng.lib" depending on the
version of cmake you have.

This example uses Qt 5.15.2 and component "MSVC 2019 32-bit" so install them and
add to path (your path may differ):

  set "PATH=C:\Qt\5.15.2\msvc2019\bin;%PATH%"

Now build zint:

  cd zint
  cmake -G "Visual Studio 16 2019" -A Win32 -DCMAKE_BUILD_TYPE=Release -B build
  cmake --build build --config Release
  cd ..

You should be able to run zint CLI and Zint Studio:

  set "PATH=%cd%\zint\build\backend\Release;%PATH%"
  zint\build\frontend\Release\zint.exe
  zint\build\frontend_qt\Release\zint-qt.exe

Note that the program name for Zint Studio when built using CMake is not
"qtZint.exe" but "zint-qt.exe".

For MSVC 2015 32 bit and MSVC 2017 32 bit, the zint cmake equivalents are:

  cmake -G "Visual Studio 14 2015" -DCMAKE_BUILD_TYPE=Release -B build
  cmake -G "Visual Studio 15 2017" -DCMAKE_BUILD_TYPE=Release -B build


Visual C++ 6
------------

The zint library and command line tool can be built using VC6.

See "win32\zint_cmdline_vc6\readme.txt"


MinGW/MSYS
----------

If not already installed, download and run the MinGW Installation Manager setup
(https://osdn.net/projects/mingw/downloads/68260/mingw-get-setup.exe/) and
using it install the packages:

  mingw-developer-toolkit-bin
  mingw32-base-bin
  mingw32-gcc-g++-bin
  msys-base-bin

(This should include mingw32-libz-dll)

Any reasonably modern version of Qt can be used. The following uses Qt 5.14.2.
Using the Qt Maintenance Tool (see the Visual Studio 2017 instructions above)
install the "MinGW 7.3.0 32-bit" component.

(Note the Qt MinGW versions actually refer to Mingw-w64, the 64-bit fork of
MinGW, but versions up to 8.1 seem to be compatible.)

Open a MinGW/MSYS shell by clicking/running e.g. (your path may differ)

  C:\MinGW\msys\1.0\msys.bat

As above make sure git and cmake are in your PATH.

Add the Qt MinGW 7.3.0 32-bit component to your PATH, e.g. (your path may
differ):

  export PATH="/c/Qt/5.14.2/mingw73_32/bin":${PATH}

Go into the directory you want to use and clone zint and libpng:

  cd <project-directory>

  git clone https://git.code.sf.net/p/zint/code zint
  git clone https://git.code.sf.net/p/libpng/code lpng

To compile lpng on MSYS, a bit of fiddling is needed. Go to the directory:

  cd lpng

On Windows git usually converts UNIX line endings to DOS ones. Undo this:

  dos2unix * scripts/*

Attempt to do the usual GNU make:

  ./configure
  make

This will fail with a syntax error. To fix:

  sed -i 's/\r//' pnglibconf.h

(ignore "preserving permissions" warning if any)

And then do the make again:

  make
  make install

  cd ..

The lpng includes should be in "/usr/local/include". Tell gcc to search there by
setting C_INCLUDE_PATH:

  export C_INCLUDE_PATH=/usr/local/include

Now we should be able to build zint normally, except for telling cmake to
generate MSYS compatible makefiles:

  cd zint

  mkdir build
  cd build
  cmake -G "MSYS Makefiles" ..
  make

  cd ../..

This creates:

zint/build/backend/libzint.dll
zint/build/frontend/zint.exe
zint/build/backend_qt/libQZint.lib
zint/build/frontend_qt/zint-qt.exe

The Zint command line tool "zint.exe" and Zint Studio "zint-qt.exe" need
"libzint.dll" to run so add its location to your PATH:

  export PATH="$(pwd)/zint/build/backend":${PATH}

You should now be able to run the command line tool:

  zint/build/frontend/zint

And Zint Studio:

  zint/build/frontend_qt/zint-qt
